Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and more specifically, to a loudspeaker with temperature adaptive protection. Background Technology

[0002] A speaker emits sound through a loudspeaker unit. The sound passes through a horn and is guided by the horn to disperse. Sound wave directivity refers to the distribution characteristics of sound energy in different directions when it propagates in space. Simply put, it is whether the sound emitted by the speaker is concentrated in a certain direction or spread evenly in all directions.

[0003] Traditional speakers guide sound waves through a fixed-shape horn, and their directivity is determined by the physical structure of the horn. The directivity pattern is fixed after the design and manufacturing are completed. The horn cannot be adjusted, which makes it impossible to diffuse high-frequency sound waves and focus low-frequency sound waves, resulting in a relatively limited application scenario.

[0004] Therefore, a speaker with adjustable temperature adaptive protection is provided. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a loudspeaker with temperature adaptive protection, comprising: a housing and a loudspeaker body; the loudspeaker body is fixedly connected to the housing; a fan is rotatably connected to the housing; a fixing block is fixedly connected to the housing; a driving component is mounted on the fixing block for driving the fan to oscillate, thereby increasing the heat dissipation area; a flow guide is rotatably connected to the housing; a first transmission component is mounted on the housing for driving the flow guide; a first rotating plate is rotatably connected to the housing; a first horn is fixedly connected to the first rotating plate; a second horn is fixedly connected to the first rotating plate; a second transmission component is mounted on the housing for driving the first rotating plate; the first horn and the second horn are arranged in opposite directions; when the second transmission component drives the first horn to move to the position of the loudspeaker body, it will focus low-frequency sound waves; when the second transmission component drives the second horn to move to the position of the loudspeaker body, it will diffuse high-frequency sound waves.

[0007] When it is necessary to diffuse high-frequency sound waves, the driving component drives the second transmission component, which in turn drives the first rotating plate to move. The movement of the first rotating plate causes the second horn to move to the position of the speaker body, thus diffusing the high-frequency sound waves. The driving component drives the second transmission component, which in turn drives the first rotating plate to move. The movement of the first rotating plate causes the first horn to move to the position of the speaker body, thereby focusing the low-frequency sound waves. Compared with the traditional non-adjustable horn, the sound waves can be focused or diffused by adjusting the switching between the first and second horns.

[0008] Further, the driving component includes: a first rotating shaft rotatably connected to a fixed block; a support column fixedly connected to the fixed block; a motor fixedly connected to the support column; a first gear fixed to the drive shaft of the motor; a second gear fixedly connected to the first rotating shaft and meshing with the first gear; a first sliding plate vertically slidably connected to the housing; a first turntable fixedly connected to the first rotating shaft; a drive column eccentrically disposed on the first turntable and fixedly connected to the first turntable; the first sliding plate includes a transmission groove; the drive column drives the first sliding plate to move through the transmission groove.

[0012] Furthermore, the first transmission component includes: a second connecting plate, fixedly connected to the first rack; a second rack, fixedly connected to the second connecting plate; and a second transmission gear, fixedly connected to the second connecting shaft and meshing with the second rack. When the first transmission component drives the fan to swing, it will simultaneously drive the second transmission component, which in turn drives the guide plate to rotate together, thereby ensuring that the guide plate swings together with the fan to ensure the heat dissipation effect of the fan.

[0013] Furthermore, the housing is provided with a first groove extending along the height direction of the housing; the first slide plate portion is located in the first groove and moves along the first groove.

[0014] Furthermore, the second transmission component includes: a cylinder, the cylinder body of which is fixedly connected to the fixed block; a push plate, which is fixedly connected to the piston of the cylinder; a second rotating shaft, which is rotatably connected to the housing; a third gear, which is fixedly connected to the first rotating shaft; and a fourth gear, which is fixedly connected to the second rotating shaft and meshes with the third gear.

The first horn 106 and the second horn 107 are arranged in opposite directions. When the second transmission component drives the first horn 106 to move to the position of the speaker body 102, it will focus low-frequency sound waves; when the second transmission component drives the second horn 107 to move to the position of the speaker body 102, it will diffuse high-frequency sound waves.

[0029] A drive component is mounted on the fixed block 104 and is used to drive the oscillation of the fan 103 to increase the heat dissipation area. The drive component includes: a first rotating shaft 108, a support column 109, a motor 110, a first gear 112, a second gear 113, a first sliding plate 114, a first turntable 115, a drive column 116, a first connecting plate 117, a first rack 118, and a first transmission gear 119.

The second gear 113 is fixedly connected to the first rotating shaft 108 and meshes with the first gear 112.

[0030] The first sliding plate 114 is vertically slidably connected to the housing 101. Specifically, the housing 101 has a first groove 101a extending along the height direction of the housing 101. The first sliding plate 114 is partially located within the first groove 101a and moves along the first groove 101a. The first turntable 115 is fixedly connected to the first rotating shaft 108. The drive column 116 is eccentrically located on the first turntable 115 and fixedly connected to the first turntable 115. The first connecting plate 117 is fixedly connected to the first sliding plate 114. The first rack 118 is fixedly connected to the first connecting plate 117. The first transmission gear 119 is fixedly connected to the first connecting shaft 103c and meshes with the rack of the first rack 118. The first sliding plate 114 includes a transmission groove 114a, through which the drive column 116 drives the first sliding plate 114 to move. The fan 103 includes a mounting frame 103a, fan blades 103b, and a first connecting shaft 103c. The mounting frame 103a is fixedly connected to the first connecting shaft 103c, the fan blades 103b are rotatably connected to the mounting frame 103a, and the first connecting shaft 103c is rotatably connected to the housing 101. A drive motor is provided on one side of the fan blades 103b, which drives the fan blades 103b to rotate, thereby dissipating internal heat.

[0031] The flow guide includes a flow guide plate 120 and a second connecting shaft 121. The flow guide plate 120 is fixedly connected to the second connecting shaft 121, and the second connecting shaft 121 is rotatably connected to the housing 101. Motor 110 drives first gear 112 to rotate, first gear 112 rotates, second gear 113 rotates, second gear 113 rotates, first shaft 108 rotates, thereby driving first turntable 115 to rotate. Turntable 115 rotates, driving first slide plate 114 to move along first slide groove 101a. Therefore, first turntable 115 drives first slide plate 114 to move along first slide groove 101a through drive column 116 and transmission groove 114a. The movement of first slide plate 114 drives first connecting plate 117 to move, first connecting plate 117 moves, first rack 118 moves, first rack 118 moves, first transmission gear 119 rotates, first transmission gear 119 rotates, first connecting shaft 103c rotates, first connecting shaft 103c rotates, fixed frame 103a rotates, thereby driving fan 103 to oscillate and increasing the heat dissipation area of ​​fan 103.

[0032] The first transmission component is mounted on the housing 101 and is used for driving the flow guide component. The first transmission component includes: a second connecting plate 122, a second rack 123, and a second transmission gear 124. The second connecting plate 122 is fixedly connected to the first rack 118. The second rack 123 is fixedly connected to the second connecting plate 122. The second transmission gear 124 is fixedly connected to the second connecting shaft 121 and meshes with the second rack 123.

[0033] When the first transmission component drives the fan 103 to oscillate, it simultaneously drives the second transmission component, which in turn drives the guide plate 120 to rotate together. This ensures that the guide plate 120 and the fan 103 oscillate together, thus guaranteeing the heat dissipation effect of the fan 103. The second transmission component is installed in the housing 101 and is used for the transmission of the first rotating plate 105. The second transmission component includes: a cylinder 125, a push plate 126, a second rotating shaft 127, a third gear 128, and a fourth gear 129.

[0034] The cylinder body of cylinder 125 is fixedly connected to the fixed block 104. Push plate 126 is fixedly connected to the piston of cylinder 125. Second rotating shaft 127 is rotatably connected to housing 101. Third gear 128 is fixedly connected to first rotating shaft 108. Fourth gear 129 is fixedly connected to second rotating shaft 127 and meshes with third gear 128. Push plate 126 includes a guide groove 126a, and part of second rotating shaft 127 is located within the guide groove 126a and rotates along the guide groove 126a. First rotating plate 105 is provided with a second sliding groove 105a extending along the width direction of first rotating plate 105, and second rotating shaft 127 moves along the second sliding groove 105a. The housing 101 includes a guide hole. A motor 110 drives a first rotating shaft 108 to rotate. The rotation of the first rotating shaft 108 drives a third gear 128 to rotate, which in turn drives a fourth gear 129 to rotate, thereby driving a second rotating shaft 127 to rotate. The rotation of the second rotating shaft 127 then drives a first rotating plate 105 to rotate. When the first horn 106 moves to the position of the speaker body 102, it focuses low-frequency sound waves; when the second horn 107 moves to the position of the speaker body 102, it diffuses high-frequency sound waves. By adjusting the positions of the first horn 106 and the second horn 107, the speaker body 102 can focus low-frequency sound waves or diffuse high-frequency sound waves.

[0035] Working process: Motor 110 drives the first gear 112 to rotate, which in turn drives the second gear 113 to rotate. The second gear 113 then drives the first rotating shaft 108 to rotate, which in turn drives the first turntable 115 to rotate. The rotation of the first turntable 115 causes the first sliding plate 114 to move along the first sliding groove 101a. Therefore, the first turntable 115, through the drive column 116 and the transmission groove 114a, drives the first sliding plate 114 to move along the first sliding groove 101a. The movement of the first sliding plate 114 causes the first connecting plate 117 to move, which in turn drives the first rack 118 to move. The movement of the first rack 118 drives the first transmission gear 119 to rotate, which in turn drives the first connecting shaft 103c to rotate. The rotation of the first connecting shaft 103c drives the fixed frame 103a to rotate, which in turn causes the fan 103 to oscillate, increasing the heat dissipation area of ​​the fan 103. This achieves the effect of temperature adaptive protection, preventing damage to internal electrical components due to overheating.

[0036] Simultaneously, the movement of the first rack 118 drives the movement of the second connecting plate 122, which in turn drives the movement of the second rack 123. The movement of the second rack 123 drives the rotation of the second transmission gear 124, which in turn drives the rotation of the second connecting shaft 121. The rotation of the second connecting shaft 121 then drives the rotation of the guide plate 120, thereby aligning the airflow direction of the guide plate 120 with that of the fan 103, thus improving heat dissipation inside the housing 101. Furthermore, the rotation of the first rotating shaft 108 drives the rotation of the third gear 128, which in turn drives the rotation of the fourth gear 129, which in turn drives the rotation of the second rotating shaft 127. This rotation of the second rotating shaft 127 then drives the rotation of the first rotating plate 105. When the first horn 106 moves to the position of the speaker body 102, it focuses low-frequency sound waves; when the second horn 107 moves to the position of the speaker body 102, it diffuses high-frequency sound waves. By adjusting the positions of the first horn 106 and the second horn 107, the speaker body 102 can focus low-frequency sound waves or diffuse high-frequency sound waves, drive the fan 103 to swing, and switch between the first horn 106 and the second horn 107.

[0037] When the first horn 106 and the second horn 107 are adjusted to the appropriate angle, the cylinder 125 drives the push plate 126 to move. The movement of the push plate 126 drives the second rotating shaft 127 to move, thereby disengaging the fourth gear 129 from the third gear 128. This causes the third gear 128 to stop driving the fourth gear 129, and the first rotating plate 105 to stop rotating. At the same time, the fan 103 can continue to dissipate heat from the inside of the housing 101, so that the housing 101 can adjust the position of the first horn 106 and the second horn 107 while dissipating heat.
